| # --description--
 | |
| 
 | |
| 这部分课程的主题是应用视觉设计。 开始的挑战基于美化一个卡片组件的外观,借此展示了若干核心原则。
 | |
| 
 | |
| web 内容大部分都是文本。 CSS 里面的 `text-align` 属性可以控制文本的对齐方式。
 | |
| 
 | |
| `text-align: justify;` 可以让除最后一行之外的文字两端对齐,即每行的左右两端都紧贴行的边缘。
 | |
| 
 | |
| `text-align: center;` 可以让文本居中对齐。
 | |
| 
 | |
| `text-align: right;` 可以让文本右对齐。
 | |
| 
 | |
| `text-align: left;` 是默认值,它可以让文本左对齐。
 | |
| 
 | |
| # --instructions--
 | |
| 
 | |
| 请让内容文本为 “Google” 的 `h4` 标签居中对齐, 然后将介绍 Google 创立历程的段落文本两端对齐。
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| `h4` 标签应有值为 `center` 的 text-align 属性。
 | |
| 
 | |
| ```js
 | |
| assert($('h4').css('text-align') == 'center');
 | |
| ```
 | |
| 
 | |
| `p` 标签应有值为 `justify` 的 text-align 属性。
 | |
| 
 | |
| ```js
 | |
| assert($('p').css('text-align') == 'justify');
 | |
| ```
